Abstract:
The invention relates to a spectrophotometry analysis device (1) comprising a test bench (4) power supply circuit (4). The analysis device comprises two different spectrophotometers (14, 18) disposed opposite the same test bench in order, in particular, to cover separate wavelength spectra included in the visible wavelength range. A first spectrophotometer (14) is used to cover the close and medium infrared spectrum, while a second spectrophotometer (18) is used to cover the ultraviolet and visible spectrum. Said analysis device is particularly suitable for dosing different components contained in fluids to be analysed (2), such as wine, fruit juice or blood-stained fluid.
Abstract:
A device for making accurate, reproducible light reflectance measurements on an optically nonuniform specimen comprises means for holding the specimen in a fixed position. In one embodiment the specimen is illuminated by light sources that are arranged at acute angles relative to the specimen and ( ± 1°) apart in azimuth, where N = the total number of light sources. The light sources are sequentially energized and deenergized to illuminate the specimen. A light detector receives light reflecting from the surface and generates an electrical signal, which is subsequently processed. In another embodimentthe light sources are arranged in pairs in which the two light sources in a pair are simultaneously energized and deenergized and the pairs are sequentially energized and deenergized. A method for measuring reflected light is also provided. The device and method are useful for making biochemical assays with reagent test strips by measuring the tone of coloration of the strips after treatment with a target substance being examined.
Abstract:
Disclosed is an illumination source apparatus comprising a high harmonic generation medium (910), a pump radiation source and a spatial filter (940). The pump radiation source emits a beam (900) of pump radiation having a profile comprising no pump radiation in a central region of the beam and excites the high harmonic generation medium so as to generate high harmonic radiation (920). The pump radiation (950) and the generated high harmonic radiation are spatially separated beyond the focal plane of the beam of pump radiation. The spatial filter is located beyond a focal plane of the beam of pump radiation, and blocks the pump radiation. Also disclosed is a method of generating high harmonic measurement radiation optimized for filtration of pump radiation therefrom.
Abstract:

Abstract:
Disclosed are an optical-characteristics measurement device and an optical-characteristics measurement method capable of reducing a measurement load for optical characteristics of a material and performing a simple and high-accuracy measurement in a short period of time. An optical-characteristics measurement device (for example, a BRDF measurement device 11) includes a light irradiation unit (for example, a light source unit 40 and a point light source 42) which irradiates a sample 16 with light, and a light reception unit which receives light from the sample 16. The light reception unit has a light reception sensor (for example, a sensor array 26) including a plurality of photoreceptors, and light guide unit (for example, an imaging lens 25) which guides light from the sample 16 to the light reception sensor. The light guide unit guides light from the sample 16 to different photoreceptors among a plurality of photoreceptors according to the position and traveling direction of light on and from the sample 16.

Abstract:
Implementations disclosed describe, among other things, a system and a method of using a wafer inspection system that includes a plurality of inspection heads configured to concurrently inspect a separate region of a plurality of regions of a wafer. Each inspection head includes an illumination subsystem to illuminate a corresponding region of the wafer, a collection subsystem to collect a portion of light reflected/scattered from the corresponding region of the wafer. Each inspection head further includes a light detection subsystem to detect the collected light and generate one or more signals representative of a state of the corresponding region of the wafer. The wafer inspection system further includes a processing device configured to determine, using the one or more signals received from each of the inspection heads, the quality of the wafer.
Abstract:
Aspects relate to mechanisms for enhancing the coupling of scattered light from a sample under test into a spectrometer. An optical device can include a reflective surface positioned apart from the sample and configured to receive a first portion of scattered light from the sample and to redirect the first portion of the scattered light back to one or more discrete spots on the sample in a non-random manner to produce redirected scattered light from the sample. The spectrometer may then be configured to receive coupled light from the sample including at least a portion of the redirected scattered light.
